The PCI6150 translates the Type 1 Configuration command to a Special Cycle and forwards the
address and data unchanged. The transaction is forwarded as a delayed transaction but the
target response is not forwarded back because Special Cycles result in a master abort. If more
than one data transfer is requested during a Special Cycle, the PCI6150 responds with a target
disconnect during the first data phase.
